Find how many minutes of video fit on a memory card at a given bitrate.
A card's megabits divided by the video bitrate gives the seconds, and dividing by 60 yields the recordable minutes. Knowing recording time before a session avoids a card filling mid-clip and informs how many cards are needed for a shoot.
Card Recording Time
Time = cards GB x 8192 / bitrate, then to minutes or hours
